Environmental risk and stock price crash risk: Evidence from energy substitution policy adoption
International Review of Economics & FinanceExploring the staggered adoption of energy substitution policy, we investigate the relationship between reduced environmental risk and stock price crash risk. The result shows that stock price crash risk decreases following the policy's passage. Moreover,

A two-stage bivariate logistic-Tobit model for the safety analysis of signalized intersections [PDF]
, 2014 Crash frequency and crash severity models have explored the factors that influence intersection safety. However, most of these models address the frequency and severity independently, and miss the correlations between crash frequency models at different ...

Anti‐Slip Material‐Based Strategies and Approaches
Advanced Materials Technologies, EarlyView.This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Identification of hazardous road sections: crash data versus composite index method [PDF]
, 2014 In current road safety practices, the identification of hazardous road sections are normally based on crash data. However, the information provided by crash data may not be adequate to explain the causal factors that lead to a crash.

Advanced Robotics Research, EarlyView.This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Nexus Between Financial Crises, Corporate Governance and Future Stock Price Crash Risk
SAGE Open, 2022 We aim to investigate the impact of corporate governance attributes on future stock price crash risk in stable and crisis periods. We used Dynamic Panel Generalized Method of Movements (DPGMM) and Principal Component Analysis (PCA) to generate the ...
